Nice and tight—that's what the Micro-Elite Chamois from Hot Chillys is all about. Its comfortable and snug fit makes it easy to layer up and brace the cold. The polyester and spandex fabric feels smooth on the skin, and the four-way stretch allows unrestricted movement. This top may be thin, but it offers some warmth, especially with its wicking ability. So, breaking a sweat on a winter outing won't end with an uncomfortably frozen trip back to the car. Expect to keep this base layer handy into spring because it's got the right qualities for less layering, too. $70; hotchillys.com.
